ultdb will not open my wad

hey i need sum help. whenever i try to open my .wad file, ultimate doom builder says that it could not open the wad for reading because "it may be invalid or open in another program." is there something wrong with my wad?

ive attached a copy of the wad to this post if anyone wants to go deep into the code

You do not have the required permissions to view the files attached to this post.

There is no need to go deep into the code.

A Doom map file (PWAD or IWAD) with the wad extension must have PWAD or IWAD as the first bytes.
For example



likewise compressed files like rar, zip, pk3 have identifying bytes

whereas your file looks like this



which is a total garble.
Hence the editor does not know what kind of file this is.
